摘要： A method for variable operation of a vehicle transmission using rough road sensing includes defining a first set of parameters to calibrate the vehicle transmission for a smooth road condition and a second set of parameters to calibrate the vehicle transmission for a rough road condition. The method includes sensing a road condition, generating a road condition signal corresponding to the road condition, and measuring a magnitude of the road condition signal. The method includes switching from the first set of parameters to the second set of parameters to operate the vehicle transmission when the magnitude of the road condition signal exceeds a first predetermined threshold. The method includes switching from the second set of parameters to the first set of parameters to operate the vehicle transmission when the magnitude of the road condition signal is less than a second predetermined threshold that is different than the first predetermined threshold.

摘要： An engine control system comprises a driver input module, a cylinder actuation module, and an active fuel management (AFM) module. The driver input module generates a fuel saver mode (FSM) signal having a first state based upon a driver input. The cylinder actuation module selectively disables at least one of a plurality of cylinders of an engine based upon a deactivation signal having a first state. The AFM module generates the deactivation signal based on at least one engine parameter and at least one threshold. The at least one threshold is modified when the FSM signal has the first state.
